'Be' it known thatil, oHN-VALDHEIMVa Elizabeth, in the county fof Unin State of N Jersey, `haveinventedcertain new and useful Improvements in Typewriting Machines,of whichthe following ijs a speciiication.` 'i' 'Ihis, invention relates `to continuous billing typewriting ymachines, and"more particulariy to nieallsf-'in machines yoflthis class for controlling ,the ifield yof theplatenlto which multiplie-'ply work-webandv the interleaved `will be incertain ofits novel `aspectafthe invention'is not limited fo 011511r5u5b115ng-machines, however.

The continuous billing` machine usually includes carbon-carrier l movable along I'a carriage-extension toward and'from the platen. mA multiple-ply 'continuous workin/ebr is introduced into the machine at the Yrear andis led forwardv through'the carbon-can rier`- to be interleaved with the carbone thereof. The web with the interleaved'can bons passes 'forward' 'A around i the revoluble platen, whichis displacedto permit straightening of the web andfcarbonsfso that Ythe carbone may be Withdrawn from the forms of av typed web-section and interleaved with the -neXt'succeeding section by pushing the carbonrcarricrl :to the rear'. The yfclafrbonfcarrieris mounted to travel toward'ian'd from the platen upon therear carriage-extension, and is arranged topartake with the."latt'er ofthe -letter-feed and return movements of the carriage. i

In some classes of work itis desirable to ruse a comparatively wide recordrshe'et with a narrow-bill-web. It maybe' desirablein accordance with the nature of'the work, to superpose the Abill-web*upon the right porti0nthe left portion, oran int`ermediate portion rof themrecord-sheet'. ",In

' vstill other 4cases it 'may be desirable to arrange the bill-web and the'recrd-sheet'in partially overlapping` relation sothat each hasv a margin extending clear ofthe other, or in nonoverlapping relation softhat they pass side by sidearound the` platen.A

It is a featurefof'the present invention that the bill-web `becaused to5 O'eupy any relation to,.therecord sheet that maybe i desiredv in a particular case VTo this end,

Y*In-,the continuous lbilling machine, which maybe of'theltype ,disclosed inthe 'patentj t Wernery &-Sn1ith,No. 1,132,055, granted March 16, 1915,y types l0 Saving upwardly and rearwardly toStrke against" the front of Lval`i"`e"v`loluble platen 11, journaled by its axle4 12 in'lafswingfranie l13"mounted in a turn directions vupon va front rail (not.

troduced into the machine over a rear bar 13 of a carriage-extension 19. This carriageextension 19 is supported at its rear by means of rollers 2O (one of which is shown) that run upon a rail 21 at the rear of an eX- tension 22 of the machine-frame 16, and includes rails 23 on which a carbon-carrier 24 is reciprocable toward and' from the platen 11. The bill-web 17 is interleaved with carbons 25 carried by blades 26 of the carbon carrier 24, and passes forward with them around the platen 11 and upward over a front paper-table 27 forming part of the swing-frame 13. At line-spacing, the carbon-carrier 24 advances with the billweb 17 toward the platen 11, and, when a bill has been completely typed, the swingframe 13 is rotated about its axis 28 to raise the platen and thus permit straightening of the web 17 so that it may be drawn forward to a gage 29 and the carbons 25 may be retracted by thrusting the carbon-carrier 24 to the rear.

For the purpose of providing a composite record of the bills, a record-sheet 30 is passed around the platen 11 in back of the bill-web 17 in position to receive impressions from the innermost carbon carried by the carbon-carrier 24. At the delivery side of the platen 11, the record-sheet 30 passes to the rear of the front paper-table 27 so that it is not drawn forward to the gage 29 with the bill-web 17 but remains stationary during this operation. Neither is it torn off with the bill-web 17 when the latter is drawn against the knife 31 after gaging. clamp, comprising a jaw 32, may be provided to clamp the record-sheet 30 stationary against the back of the front paper-table 2.7 while the platen 11 is displaced. This clamp may be like the one disclosed in the application of Jesse A. B. Smith, Serial No. 558,139, tiled May 3, 1922 (now Patent No. 1,543,731, dated June 30, 1925).

Provision is made of means for guiding the relatively narrow bill-web 17 and its interleaved cai-bons 25 to any iield of the platen desired, so that the bill-web 17 will overlie the desired portion of the recordsheet 30, in accordance with the needs of the As shown in Figure 3, for example, the bill-web 17 is positioned with its right side edge substantially flush with the right side edge of the record-sheet 30. in Figure 4, the bill-web 17 is shown with its left side edge substantially iiush with the left side edge of the record-sheet 30. These views are simply illustrative of a great number of ways in which the billweb and the record-sheet may be relatively positioned by means of the present invention.

For the purpose of enabling the billfiveb guiding means to be thus adjusted relatively to the platen, the Carriage-extension 19 is detachably connected to the carriage 14 of the machine, and provision is made of means for securing the extension 19 to the carriage in any one of a large number of positions transversely of the machine, that is, in alignment with various iields of the platen 11. At its forward end, the carriage-extension 19 is provided with forwardly-projecting hooks or brackets 33, having downwardly-opening slots 34 at their forward ends, arranged to embrace a transverse bar 35 carried by brackets 36 that extend rearwardly from the carriage 14 adjacent oppo` site ends thereof. The bar 35 has sets of notches 37 formed at intervals to provide reduced portions with which the slotted portions of at least one of the brackets 33 may interiit. The sets of notches are in this instance arranged in pairs, the sets of a pair being spaced from each other to oorx respond to the spacing of the brackets 33, but a single set would suiiice. Upon the right-hand bracket 33 there is secured a stiff spring 33 having a hook 39 at its lower end to snap beneath the bar 35 and detain the bracket or hook 33 in place thereon, so that the carriage-extension 19 will be connected to the carriage securely and yet in a yielding manner so as to permit its ready removal. The opposite end is equipped with a similar spring 38 or other equivalent means to prevent rising from the bar.

A rod 40 extends between the brackets at the front of the carriage-extension 19, and upon this rod 40 are mounted right and left side guides 41 for the bill-web 17, which may be adjusted to correspond to the width of the web 17. Right and left side guides 42 for the bill-web 17 are also mounted on the bar 18 at the rear of the carriage-extension 19, and these side guides 42 co-operate with the side guides 41 to direct the billweb 17 through the carbon-carrier 24 and to the desired field of the platen 11. Since the front side guides 41, the rear side guides 42 and the carbon-carrier 24 are all mounted on the carriage-extension 19, it will be seen that all of these parts may be adjusted at a single operation and without disturbing their (3o-operative relation to each other by removing the brackets or hooks 33 from engagement with the bar 35 and securing them in a. new position to the bar 35.

The leading-edge gage 29 for the bill-web 17 is mounted on a gage-bar 43 that is held in place on the front paper-table 27 by a knurled screw 44 threaded in to an opening 45 in the table 27. In order to enable the gage 29 to co-operate properly with the bill-web in various adjusted positions of the carriage-extension, several openings 45 are provided in the paper-table, into which the screw 44 may be threaded. The upper end 46 of the paper-table 27 is turned back and is provided with cutaways 47, the sidewalls CAD - platen.

of .which engage .and steady the ,gage-bar 43. There isone of'these cutavvavs'47 corresponding to each .of :the screw-receiving4 in, a carbon-carrier reciprocable toward and from the platen,` a track on which the carbon-carrier travels in its movement to-V Ward and from the platen, and means for adjusting the track to guide tliecarboncarrier to difierent selected fields of the 3.
